''First Orbit'' is a feature-length, experimental documentary film about Vostok 1, the first manned space flight around the Earth. By matching the orbit of the International Space Station to that of Vostok 1 as closely as possible, in terms of ground track and time of day, documentary filmmaker Christopher Riley and European Space Agency astronaut Paolo Nespoli were able to film the view that Yuri Gagarin saw on his pioneering orbital space flight. This new footage was cut together with the original Vostok 1 mission audio recordings sourced from the Russian State Archive of Scientific and Technical Documentation. The film features the music of composer Philip Sheppard. ==Production== Although the film archive of Gagarin’s training, preparations, and subsequent world tour is extensive, footage of the actual Vostok 1 flight hardly exists. In 2010 Riley came up with the idea to film Yuri’s original view of the Earth from space through the International Space Station's new giant-windowed cupola. The International Space Station (ISS) orbits the Earth once every 90 minutes, but it does not always follow the same route that Gagarin took. To find out when filming opportunities might occur, the European Space Agency (ESA) teamed Riley up with German orbital mechanical engineer, Gerald Ziegler. Ziegler discovered that the ISS covered similar ground to Gagarin's Vostok 1 spaceship approximately every week. To complicate things further, the filmmakers needed to film at exactly the same time of day that Gagarin made his flight: passing over Gagarin’s launch site, near the Aral Sea, at 06:07 UT and into the nightside of Earth over the Pacific Ocean at 06:37, before emerging into sunlight again over the Southern Atlantic at 07:10 UT and passing across the African continent and the Middle East, returning to the ground at 07:55 UT, just north of the Caspian Sea. Further calculations confirmed that opportunities to film this trajectory, with the correct sun angles, at this exact time of day, only came around once every six weeks. According to Riley, the second challenge was fitting these filming opportunities into crew time on board the space station. "The astronauts have a busy schedule; conducting a packed programme of experiments, Earth observations and activities like sleep, exercise and meal times. This meant that accommodating the extra filming request for ''First Orbit'' was yet another challenge for the ESA mission directors," he told BBC news in a March 2011 interview. On the final flight path back towards Gagarin's landing site, the scenes shot for ''First Orbit'' are slightly to the east of the original Vostok 1 trajectory. Because the vantage point is so high, the vista was similar to that of Gagarin's vantage point. Mission directors Roland Luettgens and Giovanni Gravili worked closely with the team to turn the filming opportunities into precise technical notes which translated Chris's camera directions into instructions for the crew. After a brief test shoot in November 2010, conducted by NASA's Expedition 25 astronaut Doug Wheelock, European Space Agency astronaut Paolo Nespoli filmed most of the footage for the project in early January 2011. This new footage showed the Earth as Gagarin would have seen it almost exactly fifty years before. The film does include views of the moon, though. When Gagarin flew into the nightside of the Earth on 12 April 1961, there was a crescent moon and, according to his autobiography, ''Road to the Stars'', Gagarin tried looking for the moon out of curiosity, to see what it looked like from space. Unfortunately, it was not in his field of view. The filmmakers added the moon into the scene as a tribute. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「First Orbit」の詳細全文を読む スポンサード リンク
